SLC25A22 Promotes Proliferation and Survival of Colorectal Cancer Cells With KRAS Mutations, and Xenograft Tumor Progression in Mice, via Intracellular Synthesis of Aspartate

Many colorectal cancer (CRC) cells contain mutations in KRAS. Analyses of colorectal cancer cells with mutations in APC or CTNNB1 and KRAS identified SLC25A22, which encodes mitochondrial glutamate transporter, as a synthetic lethal gene. We investigated the functions of SLC25A22 in colorectal cancer cells with mutations in KRAS.
